I've asked Dallas police for comment on security there. We'll let you know if they respond.

Update at 1:27 p.m.: Dallas police just posted this statement to the department's Facebook page:

On Sunday, April 28, 2013, at approximately 6:20 PM, an individual drove his vehicle to one of the Fixed Base Operations (FBO) buildings at Love Field. When the FBO operator opened the vehicle gate in an attempt to determine what was needed, the arrestee drove his vehicle past the FBO employee and onto the taxiway of the airport. The FBO employee immediately notified the Dallas Police Department Love Field Unit and officers arrived within minutes. The suspect had entered one of the hangers where DPD officers located him. Once the suspect was in custody, the FBI and US Air Marshal Service were notified and the suspect was charged with Criminal Trespass of a Critical Infrastructure which is a Class A Misdemeanor.

At no time were any passenger aircraft threatened by the suspect’s actions.

Original post at 11:48 a.m.: A Garland man who Dallas police found inside a secure area of Love Field airport on Sunday night struggled with responding officers and said "Jihad" repeatedly, according to police documents.

Ruben Martinez Jimenez, 36, was arrested on a misdemeanor trespassing charge. He is being held on $250,000 bail, according to jail records. That's an unusually high bond for a misdemeanor charge.

Officers were dispatched to an airport hangar about 6:20 p.m. Jimenez had entered the property through a fence, police said.

"This area is readily accessible to planes and fuel," police documents said.

Officers who confronted Jimenez said he appeared to be in "emotional distress." They repeatedly ordered him to stand up and place his hands behind his back before he began to comply, police said.

As the officers attempted to arrest him, Jimenez pushed away and, "began to resist by throwing his arms in air," the documents said.

He turned and faced an officer in an "aggressive fighting stance" and the officer responded by pulling out his collapsible baton, police said.

While waiting for additional backup, the officer said he overheard Jimenez, "yell in an unknown language and stated "Jihad" approximately three times," the documents said.

Officers were eventually able to arrest Jimenez, despite his continued efforts to fight them off, police said.

It's unclear how he was able to get into that area of the airport, which is described by police as, "a critical infrastructure facility that is completely enclosed by fence."

Arresting officers took Jimenez to the airport police station, where he was interviewed by various law enforcement authorities, police said.
